Ru‐pincer complexes were immobilized as supported liquid phase (SLP) materials to allow the methanol reforming reaction as continuous gas phase process. Under reaction conditions, the liquid phase forms from the hydroxide coating. Several hydroxides were screened and CsOH showed highest activity compared to the standard KOH coating. The well‐known Ru‐pincer complex carbonylchlorohydrido [bis(2‐di‐i‐propylphosphinoethyl)amine]ruthenium(II) is limited in catalyzing the final step of the methanol reforming. Addition of a second complex, having a methylated backbone in the pincer‐ligand, could overcome these limitations. Significant enhancement of the overall catalytic activity was observed.

用于连续气相低温甲醇重整的固定化Ru-Pincer配合物-通过第二种Ru-络合物提高活性并改变氢氧化物添加剂

将Ru-pincer配合物固定为支持的液相（SLP）材料，以使甲醇重整反应成为连续的气相过程。在反应条件下，液相由氢氧化物涂层形成。与标准的KOH涂层相比，筛选了几种氢氧化物，CsOH表现出最高的活性。众所周知的Ru-pincer络合物羰基氯氢[双（2-二-异丙基膦酰基乙基）胺]钌（II）在催化甲醇重整的最后步骤方面受到限制。在夹钳配体中添加具有甲基化主链的第二种复合物可以克服这些限制。观察到整体催化活性的显着提高。
